Ruling on standing up to do sajdat al-tilaawah

If a person is reading Qur’aan sitting down in the mosque or elsewhere, and he reaches an ayah where a sajdah is prescribed, is it better for him to stand up to do the sajdah, or should he prostrate from his sitting position? Which is better?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

We know of no evidence (daleel) to suggest that he should stand up in order to do sajdat al-tilaawah.

And Allaah is the source of strength. May Allaah bless our Prophet Muhammad and his family and companions.
